To @ZZ whom it may concern.'

Be it known that l, EARL GOODWIN Coon, of the village of FincherStation, inthe Province of Alberta, Canada, have invented certain newand useful improvements in Shockers, of which the following is thespecification.

My invention relates to improvements in shockers and the object of theinvention is to devise a simple efcient shocker which is positive in itsaction, will stand the roughest usage and be less likely to get out oforder and which will grip and support the shock from end to end, so thatthe proper shape of the shock to insure its standing upon beingdelivered is maintained until it reaches the ground.

A further object is to sodeliver the shock that all liability of tippingthe shock due to the momentum of the machine moving forward is entirelyobviated.

A. still further object is to deliver the shock through the shortestpossible space before it reaches the ground and thereby prevent to amaximum extent the spilling of the grain during its delivery to theground.

Yet another Object is to dispense with all toothed gearing, and thetrouble incident thereto.

My invention consistsl essentially in the arrangement and constructionof parts as hereinafter more particularly explained.

This invention is an improvement upon my application', Serial No.104,216.

16a indicate plates secured to the cross bar 20 so as to projectrearwardly therefrom and against which the dogs 156 are brought when therocking shaft 22 is turned so as to carry the mechanism to the positionfor delivering the shock.V

Having described the principal parts in volved in my invention 1 willbriefly describe the operation of the same.

Normally the pin 28 is in the withdrawn position as shown particularlyin Fig. 12 of the drawings and consequently there is no drivingconnection between the carrying wheel 10 and the eccentric 27. Duringthis time the sheaves are fed one at a time by the ordinary kickermechanism from the binder deck 88 over the apex of the invertedV-portion 112 to between the gripping arms 1311 and 135, one sheaf beingpushed ahead of the other until the space between the gripping arm islled. When the machine has reached the oint where it is desired todeposit the shocr the operator pulls upon the cord 166 thereby drawingthe out-turned portion 165 of the bar 35 in the same direction againstthe'tension of the spring y168 and carrying the off-set portion 37X awayfrom the rounded end of the lever 30. r1`he spring 34X forces this endof the lever outwardly and the opposite end inwardly to carry the pin 28in to one of the recesses 19 of the disk 18 secured to the hub 10X ofthe wheel 10. As soon as the operator releases the cord 166 the spring168 turns the rod 35 back to its normal position and the offset 37X intothe path of the rounded end of the lever 30. By this means the rotarymovement of the carrying wheel is transmitted to the eccentric 27, whichrotating in the eccentric strap 26, draws the pitman 25 down drawing thearm 2l1in the same direction thereby rocking the rocking shaft 22forwardly and thereby carrying the bars 38 and 39 and 11 and L12carrying the gripping mechanism and fingers 7 6 toward the positionshown in Fig. 3.

Simultaneously with this operation the` cross bar 42X secured to theforward end of the bars d1 and 12 engages the projection 102x of thelocking piece 99 forcing such locking piece downward from the position13 to the position shown in Fig. 11 thereby carrying the channel piece97 in the saine direction and forcing the link 105 downward tilting thebell crank 103 in the direction of arrow. r1`he tilting of the bellcrank 103 pulls upon the link 110 thereby drawing the arm 109 upward androcking the rocking rod 108 in a corre sponding direction. r1`he rockingof the rod 108 carries the arms 113 upward thereby lifting the cut-offplate 111 from the position shown in full lines in Fig. 6 to theposition shown by dotted lines thereby preventing any more sheaves beingfed into the machine.

1t will be noticed on referring particulai'ly to Figs. 1 and 7 that thetongue piece 137 is normally in engagement with one of the ratchet teeth1412 of the bar 1111. As the mechanism is brought into the positionshown in llig. 3 the bar 136 is forced downwardly at its rearward edgeon the hinge 136 by reason of such bar being held in the relativelystationary position by the engagement of the tongue piece 137 with theratchet tooth 142 Vduring the upward movement of the gripping mechanism.The rear-V ward edge of the bar 136 is thereby carried against the uppergripping arm 120 forcing such arm inwardly against the tension of thespring 122. Simultaneously the lower gripping ai'ni 121 is carriedtoward the upper gripping arm by means of the link connection 125connecting the upper gripping arm at one side of the center of swing tothe lower gripping arm at the opposite side of the center of swing ofthe arm. 1n order to further aid the upward movement of the lowergripping arm the pawl 1511 is forced into engagement with the ratchetrack 153 thereby tending to force the lower gripping arm' upwardly asthe gripping mechanism swings rearward and upward.

By the above described mechanism it will, therefore, be seen that thegripping forks 134 and 135V are forced together from the position shownin `Fig. 7 to the position shown in Fig. 8 the pieces 130 and 128 andlinks 131 and 129 serving to hold the forks so that they are forcedagainst the shock substantially at right angles to the shock. Alsoduring the same movement of the mechanism to the position shown in Fig.`3 the cross bar L12X engages with the fork projections 162 forcing themdownwardly and the depending portion thereof against the upper end ofthe loopmember 160 forcing the upper end of such loop member out of thehorizontal portion 96 of the slot 95.

1t will be understood that when the sheaves are fed into the machine toform the shock into the position between the gripping members 1341 and135 that the jbutt shown in lFig. 2 to the position shown in the slot 95into the vertical ,Y

Fig. 3. As the cross bar 136 is forced into the position shown in Fig. 8the curved finger 158 is carried upwardly so that the ratchet face 159is brought into engagement with the upper protruding edge of the plate61 engaging' therewith and thereby locking the gripping mechanism in theclosed position. As the eccentric 27 continues its rotary movement therocking shaft 82 is further rocked to carry the bars 38 and 39 and 41and 42 carrying the gripping mechanism and lingers 76 to the verticalposition shown in Fig. 4. As the rocked mechanism is brought into thisposition the rearwardly projecting ends of the plates 164 engage withthe tail end of the pivoted dogs 156 thereby carrying the engagingportion 156X clear of the pins 155 thereby freeing the bars 41 and 42allowing them to drop vertically and parallelly in relation to the bars38 and 39 shown in Fig. 3 to the position shown in Fig. 4. It will thusbe seen that not only the bars 41 and 42 are carried downward but alsothe cross bars 48 and 47 Vconnected thereto and the locking mechanismcarried by the depending pieces 4"X and 48X. By this downward movementof the locking mechanism, of which the bar 51 forms part, one of thepins 157 is brought into engagement with the curved finger 158 therebydrawing such ringer in a downward direction. The nger 158 beingconnected to the cross bar 136 forming part of the gripping mechanismsuch gripping mechanism is drawn downward on the guide bars 70, the eyes117X and 133 slidably moving with such guide bars.

As has been before described the gripping mechanism is held in itsnormal position by means of the tension springs 150. llVhen the pin 157is brought into engagement with the curved finger 158 the grippingmechanism is drawn down against the tension of the springs 150. Also asthe locking mechanism is carried downward as above described theshoulder 58 of the bar 55 is carried away from the rocking bar 22 andthe shoulder 57 into Contact with the opposite face of the rocking bar22 thereby forcing the bar 55 longitudinally in the direction of arrow(See Fig. 9) thereby swinging the links 64 and intoa position at anopposite angle to that shown in the drawings. As the links swingforwardly in a straight line in the direction of arrow they engage withthe inclined slot-s 62 and 63 of the. plate 61 thereby drawing the plateinwardly in the direcv tion of arrow (see Fig. 10) and out of engagementwith the ratchet face 159 of the linger 158 thereby releasing suchlinger-which is forcedrback to the normal position by means of thetension spring 122, which draws the gripping ends of the gripping jaws120 and 121 apart forcing the cross bar 136 upward to its normalposition. By the same movement the linger 158 is carried clear of thepins 157 so that the springs 15() draw the gripping mechanism upward,the eyes 117 and 138 sliding upward over the guide bars 70. By thisoperation the mechanism is brought from the position shown in Fig. 4 tothe position shown in Fig. .57 thereby clearing the shock. As themachine. passes forwardly the lingers 76 are drawn outwardly frombeneath the shock. lVhen in this position the eccentric 27 has made itscomplete downward throw and as it passes over the center the rockingmovement of the rocking bar 22 is reversed thereby carrying the bars 38and 39 and 41 and 42 carrying the gripping mechanism and lingers 76 in.the reverse direction or in the direction indicated by arrow in Fig. 5,as the mechanism is carried upward away :from the iingers 83. Theseiingers now being relieved of the weight of the sheaves are drawn upwardby means oit the tension spring 87 to their normal position therebycarrying the loop member 160 back to its normal position in thehorizontal portion of the slot 96. .By the further upward movement thebar 42X is brought into contact with the upper projecting portion of thelocking piece 99 thereby swinging it out of the recess 98 and drawing itvertically upward against the inner face of the vertical member 92 backto its normal position.

In order to insure of the return upward movement of the iingers 88 thecross bar 42X is brought into engagment with the inturned portions ofthe rods 84 thereby positively drawing up the fingers 88 to their normalposition. When the bars 41 and 42 drop downward and are brought to thevertical position as above described the rollers 44 are brought intoengagement with the track 45 and as the return rocking movement isperformed these rollers travel over the tracks 45 and as such tracks areeccentrie to the center oi movement, that is to say, graduallyincreasing in radius rearward the bars 41 and 42 are gradually drawnlongitudinally upward in relatirm to the stationary bars 88 and 89carried by the rocking bar 22.

It will also be understood that by the upward movement of the lockingpiece 99 back to its normal position as above described that the bellcrank 103 is swung in the opposite direction to arrow (see Fig. 13)thereby carrying the cut-01T plate back to its normal position or theposition shown by full lines in Fig. 6. This operation is performed byone complete revolution of the driving wheel 10 when in drivingengagement with the eccentric 27. At the completion of the aboveoperation and the consequent completion ofi the revolution of thedriving wheel 10 the rounded end of the lever 30 is brought intoengagement with the oiset portion 37X realises' thereby forcingthat endof the lever to ward the eccentric against the compression of the spring34X and the opposite end away from the -eccentric so as to draw the pin28 out of the corresponding recesses 19 and allow the driving wheel 10to again run free. 1f during the depositing of the shock more than onesheaf is collected on the de livery end of the deck 88 such eXtra sheafwill be forced up between the raised cut-off plate 111 and the loopmember 116 into the loop of such member and `will be retained in suchloop until the cut-off plate is again lowered to feed the sheaves intobetween the gripping forks 134 and 135.

1n order to adjust the shock gripping mechanism longitudinally of theshock in accordance with the length of the shock so that the sheafgripping forks will grip it at the proper point all that it is necessaryto do is tov withdraw the pin 148X and adjust the lever 138X so as torock the bar 138 and arms 140 carried thereby so as to carry the notchedbar 141 longitudinally of the machine. 'if it is desired to adapt thegripping mechanism to a longer shock when this adjustment is made thetension springs 151 will serve to draw the tongue plates 137 intoengagement with the corresponding notch. 1f, however, it is desired toadapt the position of the gripping mechanism from the long shock to ashort shock it will be first necessary to force the gripping mechanismforwardly against the tension of the springs 151X and then adjust thenotch bars by means o-f the lever 138X to the required position so thatthe tongue plates 137 will engage therewith. lt will be readily seenthat if the mechanism is adjusted for a long shock the plate will engagewith one of the lower notches but if adjusted for a shorter` shock itwill engage with one of the upper notches as the bar 141 is swunginwardly or outwardly.

From this description it will be seen that 1 have devised a very simpleform of shocker in which all gears are dispensed with and which may beoperated so as to deposit the shock in a secure and stable position atany point desired and the shocks set up in rows convenient forgathering.
